DYEIN'G APPARATUS Application filed October 1,1930. Serial No. 485,616.

This invention relates to dyeing apparaf tus, and more particularly toapparatus for the partial or multi-color dyeing of wound masses of yarn.

A particular object of the invention is to provide for applying theso-called Eclipse- I Van Ness hydraulic method of dyeing described inVan Ness U. ,8. Patent No.

1,456,344 to the partial or multi-color dyeing of packages of rayonyarn. It has been found that the particular injecting apparatusdescribed in said Van Ness U. S. Patent No. 1,456,344 and in the laterVan Ness Patents, Nos. 1,577,884 and 1,606,196, while highlysatisfactory in the dyeing of otherkmds of yarn, is not applicable tothe dyeing of rayon yarn becausethe construction of the plicable torayon, the use of the new machine is by no means limited to dyeingrayon, as it may be applied to all other kinds of yarn.

The invention will be further explained in connection with a detaileddescription of a practical dyeing machine embodyingthe invention andillustrated in the accompanying drawings, in which: I

Fig. 1 is a plan view with the'base plate partly broken away, showingthe yarn mass spaced from the injectors;

Fig. 2 is an enlarged longitudinal section taken on the line 22 of Fig.1, and showing the yarn mass in position for dyeing;

Fig. 3 is a partial transverse section taken on the line 3-3 of Fig. 1,showing the pump;

Fig. 4 is an enlarged horizontal section taken on the plane of the axesof the dye nozzles, which is indicated by the line 4-4 in Fig. 5; and

Fig 5 is a front elevation of thepresser and injector nozzles.

a multi-color dyeing machine similar in general construction to thatshown in my Patent No. 1,726,984. It includes a baseplate B carrying amulti-cylinder pumpP and'a workholder W. In the operation of themachine, the pump draws-different colored dyes from aplurality ofseparates reservoir'sTa, Tb, T0 andToZ, and forces limited quantities ofthe different colored dyes into separate portions-of a mass of yarn onthe workholder N through a plurality of nozzles J in a presser .A whoseconstructlon constitutes a particular feature of the invention.

The means for operating; the pump andfor supporting, translating androtating the spindle of the workholder are identical with 'thosedescribed in my Patent No. 1,726,984,

The machine illustrated in the drawings is to which referenceis made-fora detailedzdescription of these parts which maybe readily applied tothedrawingsof the present application, since the reference numerals used insaid patent have been applied to the identical or corresponding partsshownin the drawings ofthe present application. It should holder W isprovided with a cylindrical extension VV4 adapted to fit the bore ofacylindricalbobbin or. core C1.

The portions of the machineillustrated which cooperate directly with theyarn differ from those shown in my patent above referred to. The yarnmass C consists of a thin,

hollow, cylindrical layer wound on a cylindrical core 01 whose radius isseveral times as great .as the depth of the yarn mass. The

ings P24 of thepump cylinders. The outer:

vertical surface A1 of the presser is concave and cylindrically curved,having substantially the same radius as the outer surface of the yarnmass C, so that, it is adapted to fit evenly against a portion of thecircumate-zones of "the compressed portion which separate the partsof-this portion into which ferential surface of a yarn mass from one endof the mass to the other. The presser contains a plurality of holes orbores A2 extending through its surface A1 and connected in groups bypassages A3 with the outlet openings PM of the pump cylinders. In theouter end of each bore A2 is seated a nozzle A4 which most desirablyprojects from-the surface A1 of the presser.

It will readily be understood'that, when the workholder Wis operated to'm'ove'the yarn mass toward the pump into the position shown in Fig. 2,the surface A1 of the presser A fits against the circumferentialsurfaceof the yarn mass 0 and evenly compresses an extended portion of thissurface. While the machine operates verysatisfactorily with a portion ofthe yarn thus evenly compressed,

"anadv'a'ntage is gained by 'p'roviding "foran additional compression ofnarrow mtermedidifferent colored dyes are injected. Inthe machineillustrated, such additional com- \pression: is secured byiprovidin'gthe pressing surface A1 of the presser A with projecting transverseridges A5, which are located between the sets of nozzles A4communicating with the-.dilferent pump cylinders. I

The use of themachine from the operators ,point of viewis'the sameasthat described inPmy-Patent No. 1,726,984. The workholder is'reciprocated towards and away'fromthe lpu'mp. At the end of each inwardstroke, a 335;

portion: of the :yarn is evenly compressed by the surface A1 of thepresser A, and the pump then makes one compression stroke which forcesthe dyesof different colors under equal pressures intodiiferent parts ofthis evenly 'compressedportionof the mass. The shaft -of the workholderis rotated slightly'after each outwardstroke, so that successive sectorsof the mass are dyed in four colors until at "the end of the operationthere are'four-bands .%45-

ofdifferent colors extending around the mass. The pressure exerted I bythe pump pistons "issufficie'nt to cause the dye injectin g'from eachnozzle to penetrate through the shallow ma s's from its outer to itsinner surface in i the absence of any mechanically opened passage forthe'injected dye. This, combined with theevenfpressureon'theportion ofthe mass being dyed, results in a very'even spreading ofthe dye.'By'proper adjustment of the between thedifl'erent colored bands-in themass, avoiding any undyed portions between the bands andanysubstantialoverlap-ping or mixing of the colors; The dyeing thecompressed portion in the absence of i my hand.

in each band is uniform from the outer surface to the inner surface ofthe mass.

What I claim is:

I 1. Apparatus for dying a wound mass of yarn, comprising a presserhaving an extended concave surface formed tofit against a.circumferential surface of the mass of yarn seas-evenly to compress aportion of the mass, and means for injecting dye through the presserinto a portion of the'yarn'compressed 'by said surface 2. Apparatus fordyeing a. wound mass of yarn, comprising a presser having an extendedconcavesurface adapted to fit against a surface of the mass so as evenlyto compress "a portion of 'the m'a-ss, a plurality of nozzles'p'rojecting from said surface of the 'presser,*anduneans for injectingdye through said nozzles simultaneously into -a portion of 'the masscompressed by the presser.
